Figures published on Thursday show Mr Palmer attended just 17 of 33 sitting days between August 26 and December 4.
His attendance was the worst of any MP in 2014,when Mr Palmer was present for 49 days of parliament,but missed 27.
Mr Palmer has come under scrutiny for his attendance since winning the seat of Fairfax.
On Thursday,he said his poor attendance during the spring session was due to the birth of his second child with wife Anna.
Mr Palmer put his overall attendance down to political tactics.
He said as the only Palmer United Party member in the House of Representatives he did not want to participate in votes that would reveal his bloc's voting intentions in the Senate.
"Since we've got the Senate I haven't wanted to vote on things that would undermine our voting position and power in the Senate,"Mr Palmer said.
